We carry a wireless printer and I set up a network with an old wireless router. It is only a network for sharing files with the printer and has no internet capabilities but works great. We keep the printer in a cupboard Out if the way.

I carried a printer/scanner as I worked some from the road. I used it all the time. Even found a small fold up desk to use with the laptop as well. When you get home, just take it out due to the temps and it should last you a long time.
